Purpose -The purpose of this paper is to investigate ways to attract and retain knowledge workers in a globally successful knowledge city or a city aspiring to become one.Design/methodology/approach -The paper reviews the literature on knowledge work and workers and provides useful recommendations on the fundamentals of how to attract and retain knowledge workers.Findings -The paper sheds light on attracting and retaining knowledge workers that knowledge industries, knowledge-based development and knowledge cities rely on. Originality/value -The paper provides an in-depth discussion on the concepts of knowledge work, knowledge workers and what these workers want when they are not at work.

Background: Few studies have been conducted to investigate the impact of extreme cold events on mortality in subtropical regions.Objective: In the present study we aimed to investigate the effects of the 2008 cold spell on mortality and the possibility of mortality displacement in three subtropical cities in China.Methods: Daily mortality, air pollution, and weather data were collected from 2006 to 2009 in Guangzhou, Nanxiong (no air pollutants), and Taishan. We used a polynomial distributed lag model (DLM) to analyze the relationship between the 2008 cold spell and mortality. To observe the mortality displacement of the cold spell, we estimated the cumulative effects at lag0, lag0–6, lag0–13, lag0–20, and lag0–27 separately.Results: During the 2008 cold spell, the cumulative risk of nonaccidental mortality increased significantly in Guangzhou [relative risk (RR) = 1.60; 95% CI: 1.19, 2.14] and Taishan (RR = 1.60; 95% CI: 1.06, 2.40) when lagged up to 4 weeks after the cold spell ended. Estimated effects at lag0–27 were more pronounced for males than for females, for respiratory mortality than for cardiovascular mortality, and for the elderly (≥ 75 years of age) than for those 0–64 years of age. Most of the cumulative RRs increased with longer lag times in Guangzhou and Taishan. However, in Nanxiong, the trend with cumulative RRs was less consistent, and we observed no statistically significant associations at lag0–27.Conclusion: We found associations between the 2008 cold spell and increased mortality in the three subtropical cities of China. The lag effect structure of the cold spell varied with location and the type of mortality, and evidence of short-term mortality displacement was inconsistent. These findings suggest that extreme cold is an important public health problem in subtropical regions.

It has been argued that the global city-social polarisation thesis put forward by scholars looking at North American cities cannot be easily transferred to global cities in other parts of the world. Recent research has illustrated that whilst there may be some change in levels of social polarisation in global cities outside the US, the form, structure and causes of social polarisation are different. This paper extends the debate by looking at Sydney, Australia. It is argued that whilst changes in occupational structure and income polarisation are partially explained by economic restructuring associated with globalisation, global processes alone cannot fully explain these changes. The paper points to the significance of the inclusion of factors such as the unemployed, the gendered structure of occupations and migration.
